LANTERN FOR MOVING PICTURES.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed October 15, 1914. Serial No. 886.765.

To all whom it may concern:

Be it known that I, ABRAHAM J. STONE, a citizen of the United States of America, residing at the city of Albany, in the county of Albany and State of New York, have in vented certain new and useful Improve ments in Lanterns for Moving Pictures, of which the following is a specification.

My invention relates to apparatus for displaying pictures upon a screen by means of a projection lamp or other suitable device, and the object of my invention is to provide a means for displaying around a picture a suitable frame or border displayed by a moving picture lamp, with means for changing the color of the frame or border, and means for displaying a legend, name or designation at the top, bottom or side of the picture displayed by a lantern; together with such elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish these objects by means of the mechanism illustrated in the accompanying drawing, in which Figure l is a plan. Fig. 2 is a se'ption along the lines X-K on Fig. 1. Fig. is a plan of the adjustab e slide, S Fig. his a the adjustable slide, S. Fig. 5 is a plan of the reverse side of the adjustable slide, S.

Similar letters and figures refer to similar parts throughout the several views.

To the lamp house, A, containing the projection lamp, B, for displaying a picture upon a screen, I attach by suitable bolts, (z, a, a plate, K, to which is secured the lens case, C Light from the side of the lamp, B, will shine through the lens case, C, and be reflected by a mirror, D, which mirror is rotatably mounted in an arm, at, attached to the lenscase, C. In the lens case, C, I place a lens, E, of any desired form. The post, F, is slotted near its outer end at 7, through which. slot a rod, G, extends, on the end of which rod is a thumb screw, 9, adapted to be secured in contact with the sides of the slot, f, there being a nut or shoulder, H, formed on the rod near the thumb screw, 9. The rod, G, is attached to acollar, J, passing around the neck of the lens case, C. The lens case, C, is adjustably secured to the plate, K, by means of the collar, L, which embraces the lower portion. of the lens case, C, the lens case passing through an enlarged opening in the plate, K, the collar, L, being secured to a plate,

W, adapted to slide in the groove formed by the over-turned edge of the plate, is, upon which the plate, WV, rests. The plate, K, is adapted to move in the groove, U, in the plate, V, which rests upon the plate, K. Thus the lens case, C, may be adjusted to its position in reference to the lamp, B, by movement in one direction in the groove, U, in the plate, V, and in the opposite direction on the plate, 70, guided by its over-turned edge.

To a post, M, I secure an N, carrying a rod, 0, upon which is mounted a lens, P. The rod, 0, is adjustable in the arm, N, and held in position by a suitable thumb screw, m. The lens, P, is ad justable in the arm, N, held in position by the thumb screw, 79. The lens, P, is placed in such position that the reflection from the mirror, D, will pass through the lens and be projected upon the screen (not shown).

In the lens case, slide, S, preferably holding it in position by means of the frame, T, secured to the side of the lens case, 0, b 1 the rivets, 25, 2?. Adjustably supported in the frame, T, is the movable recessed plate, X, which is capable of movement within a frame, T, and a short angled piece, Y, attached to the frame, T, and to the side of the lens case, C, by the rivets, t, t. My slide is made up of two adjustable side pieces, 1 and 2, each provided with slotted ends, 4, 4. The bolts or rivets, 5, are placed through each of said slots into the frame, 6. Between the side pieces, 1 and 2, the light from the lens will pass, except at the central tion where it will be intercepted by the adjustable block, 7. The width of the space between the block, 7, and side pieces, 1 and 2, will depend, of course, upon the position the slides, l and 2, occupy with respect to each other, as well as the degree to which the block, 7, is expanded or contracted. W' hen the side pieces are drawn toward the center there will not be so much light passing around the sides of the block, 7 as when the pieces, 1 and 2, are farther apart. And, of course, when the block, 7, is contracted there will be more light than when it is expanded to the condition shown by dotted lines in Fig. 3.

in order to regulate the of light delivered at the top the picture, I arrange the amount and bottom of por- A adjustable arm,

C, I place the adjustable slot formed between the slides, 8 add 9, at the 1 top and bottom of the frame, 6, and have the ends slotted at 10, 10, the bolts or rivets, 11, passing through the slots into the frame, 6, whereby ,the slides, 8 and 9, may be .mcved to or from each other with the adjustable block, 7, and thus regulate the quantity of light that will be delivered at the top or bottom of the picture.

The block, 7, is made up of four rightangled plates, 20, 21, 22, and 23, which are suppdrted between two parallel plates, 24,

25. Thus the plates, 20, 21, 22, and 23, may

be 'drawn uutwardly from the plates, 24, 25, so that they will occupy the position shown by dotted lines in Figs. 3 and 5. Passing through the plates, 24, 25, is the screw, 27, provided with the nut, 26, so that by loosening the nut, 26, the plates, 20, 21, 22 and .23, may be moved, and by tightening the nut 26, they may be held in the desired position in which they are placed.

As thus arranged, when the light from the lamp, B, is/thrown from the lens, E, there will be reflected on the mirror, D, a border of light of a width equal to thedistance between the block, 7, and the inner side of the side pieces, 1 and 2, and slides, 8 and 9. This border of light will be thrown into the lens, P, which lens will be projected to theypicture on the screen so that this border of light will surround the picture displayed by the lamp, B, on the screen, ,making' a finishing border for the picture.

",Inl order to provide a color for this border,

i arrange a disk, 12-, containing a series of 'colored glass, 13, which is mounted on a suitable rod, 14:, and arranged so that the desired color may be placed in fsont of the lens, P, whereby the light emitted from that lens will, when projected on the screen,

display the color of the glass in the disk through which it passes. Instead of col- ,ored glass I may place a name, legend, advertising matter or any wording desired on e transparent part of the disk, and thus cause that to appear on thescreen adjacent to the picture from the projection lamps.

By my invention, without the cost of procuring and operating an additional lamp, I am enabled to put upon the screen a suitable ;frame for my pictures which adds to .-the artistic'qualities of the picture, and just as a' frame upon' a painting m'akes'the painting appear more attractive andindeed brings oupL the ,colors and shades of the picture, so suitable frame upon a picture displayed on a screen adds tojits attractivetress and effectiveness. What I .claim as my invention and desire to secure by Letters Patent is:

l. A lantern adapted to display a pic ture from a lamp housing in which the lanternfis mounted; with a lens case;'means for attaching the same to the said lamp housing; a lens in said case; an adjustable slide in said case; a mirror placed in position to receive the light from said lens; means for adjusting said mirror; "a lens adapted'to receive the reflection from said mirror; means for adjusting said last men tioned lens; and a disk containing a transparent portion with matter for display placed thereon adapted to'be placed in front of the last mentioned lens, described. g

2. A device for projecting a border on a picture, comprising a lantern for displaying the picture on a screen; a lens mounted at substantially as the side of said lantern; an adjustable slide comprising four movable strips, one on each side and one at ea'ch end of the adjustable slide; with means for moving. said strips to and from the center of the adjustable slide; with a central adjustable, opaque' portion in said adjustable slide, comprising four plates adapted to be drawn obliquely from the four corners of the central portion,

thereby extending the sides and ends of the central portion; with means for clamping and holding said adjustable. plates in the de-. sired position; a mirror adapted to receive the light projected around said adjustable slide; a lens mounted to receive the reflection from said mirror; and means for-ad'- justing said last mentioned lens, substantially as described; I
